Clinical aspects of renal transplantation.

Progress in kidney transplantation is not so much hampered by the difficulties of the surgical procedure as by the problems of immunologic rejection and the complications of the immunosuppressive treatment. The radiologic investigation is an indispensable tool for the diagnosis of these, often life-threatening, complications and transplantation programmes cannot function adequately without the help of experienced radiologists. Further improvement in kidney graft survival awaits a breakthrough in the knowledge of the immunological phenomena that govern the rejection reaction.
